Commit c4ba68b8691e4 backported from upstream to 4.14 stable was
probably applied wrongly, and instead of calling sfp_register_socket in
sfp_probe, the socket registering code was put into sfp_remove. This is
obviously wrong.
The commit first appeared in 4.14.104. Fix it for the next 4.14 release.
Fixes: c4ba68b8691e4 ("net: sfp: do not probe SFP module before we're attached")
